Abstract

Wireline plugs for use in a Y-tool. In some embodiments, the wireline plug can include an elongated body defining a bore therethrough. A first end of the elongated body can include an outer surface configured to serve as a fishing neck and a second end configured to connect to a downhole tool. The wireline plug can include an elongated seal defining a bore therethrough disposed within a portion of the bore defined by the elongated body. The elongated seal can be configured to provide an at least partial fluid seal between an inner surface of the bore defined by the elongated body and an outer surface of a wireline when disposed within the bore defined by the elongated seal. The elongated seal can be formed from a polymer, an elastomer, or a combination of a polymer and an elastomer.
